| 摘 要： | 本文比较了~35S同位素标记法和两种常规化学分析、一种电化学分析法测定环境样品中SO_4~2-的优劣.用本法和BaCrO_4分光光度法研究土壤对SO_4~2-的吸附-解吸特征,表明两者测定结果接近,且所得规律一致.酸雨研究中,在样品数量多、SO_4~2-分析任务重且仪器、设备条件具备时,本法为便捷、准确、较理想的SO_4~2-测定技术.

| Abstract: | The advantage of determination of SO42- by a labelling method with 35S in comparison to two conventional chemical analysis or an electro-chemical titration method was described. The tested results obtained by this method could be suggested that it was a speedy and accurate monitoring technique for sulfate determination of environmental samples. |
